摘要
为了体现非晶合金低损耗性能的优越性,对1台15 k W、1 000 Hz电机进行空载铁耗仿真计算分析。电机定子铁心为非晶合金材料,定子铁心采用浸漆、固化加工工艺。电机空载铁耗的计算主要包括非晶定子基本铁耗的分离以及空载杂散损耗的计算,得出了非晶合金电机杂散损耗是基本铁耗的6.03倍;并与定子为50DW310时进行对比,得出空载运行时,非晶合金空载铁耗约为硅钢片50DW310的18.82%,电机的效率可以提高3.48个百分点。
In order to reflect the superiority of low-loss amorphous alloy,a 15 kW,1 000 Hz motor was used to perform no-load iron losses simulation.The motor stator core was made from amorphous alloy,and treated with dipping coating and curing process.The motor no-load iron loss calculation includes the separation of basic iron loss of amorphous stator and the calculation of no-load stray losses.It was obtained that the amorphous alloy motor stray loss was 6.03 times of the basic iron loss.Comparison was made with the 50DW310 stator.Under no-load operation,the amorphous alloy no-load iron loss was about 18.82%of silicon steel 50DW310 no-load iron loss,and the motor efficiency could be increased by 3.48 percentage points.
